When an Eye Exam Uncovers a Tumor

Did you know that an eye exam can uncover a serious medical condition that requires immediate treatment?   I had a patient come in for his annual exam, reporting that his vision had been gradually getting worse. Peripheral vision testing uncovered a defect in both eyes, which is usually caused by a mass compressing the optic chiasm.   A prompt referral for a MRI revealed a tumor on the pituitary gland, which sits beneath the optic chiasm.  The tumor was so large that it affected many structures inside the orbit. In 2 weeks, a neurosurgeon performed the risky, delicate surgery to remove the tumor. Thankfully, the surgery was successful and his vision is slowly recovering.
